The vibration direction converter is made to be disassembled or assembled, so that the replacement of the rod is easy when it experiences vibration fatigue. Efficiency is maximized because plural welding operations can be made simultaneously, since plural vibration-transmitting directions due to a symmetrical multiple structure are possible by means of the vibration-direction converter. ## Claims ### Claim 1 A welder using an ultrasonic vibration, comprising: an oscillator for generating an electrical frequency; a vibrator for converting the
